Annotation

In order to reveal the spatio-temporal variability of the composition of fresh groundwater, 4 regions were studied, differing in natural and technogenic conditions. It was revealed that in agricultural areas there were no particularly significant changes in the composition of groundwater over time (the last 60 years). Within the oil refining industrial zone, intense pollution of groundwater is observed only in the vicinity of sludge reservoirs and waste landfills, while pollution is local in nature and does not extend further than 1.0-1.5 km in the direction of filtration flows. One of the reasons for this is the high buffer capacity of the geological environment. The compositions of fresh groundwater in the territory of intensive oil development were subjected to the most negative transformation over large areas. Depending on the values of temporal concentration gradients, 4 degrees of change in the composition of groundwater are distinguished: “extremely weak”, “weak”, “medium” and “high”. Of these, the last two are manifested in the central parts of the oil-bearing areas, where the mineralization of groundwater in the upper part of the section can reach 10 g/l, and the hardness is 70 mmol/l.
